Filter XML SQL query result

I have an XML column:

 

<xmlList> <XMLEntity> <sug>ACHR</sug></XMLEntity><XMLEntity> <sug>DOA</sug></XMLEntity></xmlList>

 

The sug can hold only a enum memeber(ACHER or DOA). I would like to check if there is a sug without one of these values.

In this way I get the sug node where they are not from enum values:

 

SELECT XMLSERIALIZE(XMLQUERY ('//xmlList/XMLEntity/sug[.!=ACHER" and .!="DOA]'passing KTOVET ) as char large object) as XXXFROM "TABLE"

 

The result is OK, but wherever the sug is ACHER or DOA I get empty line. How can I avoid the empty lines from result?
